The alkaline Meidob volcanic field is a volcanic field at the northeast end of the Darfur volcanic province in western Sudan. It covers an area of 5000 km2 with nearly 700 late Cenozoic vents. The volcanic field was constructed over an uplifted Precambrian igneous and metamorphic basement and is elongated in an east-west direction. Basaltic scoria cones and associated lava flows dominate, but trachytic-phonolitic lava domes, tuff rings, and maars are among the youngest volcanic products. The lava from the scoria cones produced a broad lava plateau. The central part of the field consists of younger phonolitic lava flows, trachytic pumice-fall deposits, ignimbrites, and maars. The youngest dated eruptions about 5000 years ago produced a tuff ring and a lava flow.
